ADG3308BRUZ (ANALOG DEVICES)

The ADG3308BRUZ is a 8-channel Bidirectional Logic Level Translator used in multivoltage digital system applications, such as data transfer between a low voltage DSP controller and a higher voltage device. The internal architecture allows the device to perform bidirectional level translation without an additional signal to set the direction in which the translation takes place. The voltage applied to VCCA sets the logic levels on the A side of the device, while VCCY sets the levels on the Y side. For proper operation, VCCA must always be less than VCCY. The VCCA-compatible logic signals applied to the A side of the device appear as VCCY-compatible levels on the Y side. The enable pin provides three-state operation on both the A pin and the Y pin. When the EN pin is pulled low, the terminals on both sides of the device are in the high impedance state. For normal operation, EN should be driven high.
